Harmonic Highlights:
- Features a characteristic descending chain of dominant 7th chords (e.g., Gm7-C7, F#m7-B7), often functioning as secondary dominants or tritone substitutions.
- Frequent use of altered dominant chords (Ab7#5, B7#11) introduces chromatic tension and unexpected voice leading.
- Employs numerous ii-V progressions that quickly tonicize new key centers, moving dynamically through non-diatonic harmony.
Improvisation Focus: Navigating the rapid chord changes by targeting chord tones and employing altered scales and chromatic approaches.
Difficulty Rating: 5 (Advanced) Requires sophisticated understanding of tritone substitutions, altered dominants, and navigating fast-moving, non-diatonic progressions.
